Industrial sites are subject to regulations that limit sound and vibration levels at their perimeter and with regard to third parties. The taking of measurements at intervals remains one of the most frequently used methods of evaluating the noise and vibration levels of such sites.

Real time monitoring of structures is an excellent field of application for wireless sensor networks. ADVANTICSYS has provided solutions for the monitoring of structure in different fields, from bridges, where the vibration has to be controlled both in the construction and operation phase, to cultural heritage buildings with their structural integrity under risk.

The nuclear industry must increase the availability and reliability of its power stations whilst ensuring that a high level of safety is maintained. The principal weak points in achieving this objective are the industry`s systems and components.

State of the art noise monitoring systems; Modern noise monitoring systems offer a wide range of advanced features and come with software that can analyze and structure long term measurements data efficiently. A complete noise monitoring system consists of one or more noise monitoring terminals, a noise server and work stations for presentation, post processing and reporting.

One of the largest acoustic consulting firms in Australia was engaged by the New South Wales Department of Planning & Industry to conduct wind farm noise assessments. The goal was to perform a specialist, independent acoustic compliance audit of three major wind farms located near Canberra, Australia’s capital city.
The objective of the study was to conduct a detailed noise assessment at residential dwellings near to the wind farms. Three wind farms near Canberra, Australia, were investigated.
XL2 Sound Level Meters were operated on a continuous basis, typically over a six week period at each wind farm. The XL2 was battery powered to enable continuous noise logging for two weeks at a time at each residential site. The recorded data was then processed in accordance with the relevant standards specified in the conditions of consent for wind farms.

Certain leisure activities, and motor sports in particular, are a source of elevated noise levels. They cause significant disturbance for nearby residents, particularly as such sites are being developed in increasingly densely populated urban areas.

Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture, economy and politics. We offer solutions to cover all demands from level checks to in-depth analysis, from measurement or prediction, to post-processing and reporting.

Vibration is simply defined as the variation of an object about a fixed position. To properly define and quantify the physical characteristics of vibration, however, is much more complex - account must be taken of the direction, frequency and magnitude of vibration. Then, what properties should be measured? Is it appropriate to measure the displacement of the vibrating object as a measure of its amplitude, or should we instead measure velocity, or acceleration? What are the conventions for measuring direction, and is it really important?

The oil and gas industry requires major infrastructure in terms of refineries and offshore extraction platforms which operate continuously. A large number of essential rotating machines, structures and piping networks are subjected to high levels of demand in a difficult environment, leading to the potential for breakage.

Workplace noise monitoring is an interesting subject that can appear complex, but it is always worth remembering what you are trying to achieve. This can be summarised as: ““Minimising or avoiding the risk of noise-induced hearing loss in the workplace to comply with local, noise-based, legislation”” Such legislation is usually based on a European Directive that is then modified to suit the needs of each particular country. For example, in the United Kingdom, the ‘The Control of Noise at Work Regulations 2005’ are based on the European Union Directive 2003/10/EC; usually called “The physical agents (noise)” directive and expanded upon by the Health & Safety Executive.

By implementing a noise and vibration monitoring system, the impact of construction site activities can be managed by: Complying with legal requirements relating to public health sanctioning the absence of appropriate precautions to limit abnormally high levels of noise and vibrations. Taking environmental quality considerations into account (HQE approach). Limiting noise and vibration pollution with the comfort of neighbouring residents in mind. Enabling companies in the public works and construction industry to adopt a transparent approach to communication with local residents, in order to avoid resistance and instead gain their support for a given project. Providing the site manager with reliable and official data, should it be required. 01dB offers solutions for construction professionals to suit the requirements of each building site. It provides them with metrological systems (such as the certified DUO sound level meter, dB4 and MR2002) with 01dB WebMonitoring services to ensure optimal control of noise & vibration impact of the construction work, using as well communication tools intended for the general public.

Vibration testing is is used for aerospace and defence testing, ground transportation, transport simulation, package testing, altitude simulation and more. Our comprehensive range of LDS electrodynamic shakersare designed for vibration testing of devices of any size - from a semiconductor component to a complete satellite system, to see how it will stand up to real-world conditions. With an LDS vibration test system your shaker, power amplifier, vibration controller and even environmental chamber are not only controlled from one PC, they run under one software package. Combined with data acquisition systems and analysis software suites, Brüel & Kjær ofers the complete vibration testing solution to establish proof of quality according to national and international standards, such as DIN, ISO, BS, MIL, IEC and ASTM.

Norsonic is a world-leading supplier of sound measuring equipment for the motorsport industry. We have a long experience in supplying sound measurement solutions for racetracks, ranging from single noise monitors to large multichannel monitoring solutions with sophisticated reporting system.

The paper industry depends upon a continuous industrial process in which the paper machine is the central factor. This system is based on several variable speed rollers mounted on roller-bearing blocks, and damage to a single block can be enough to shut down production for several hours.
